H. c. KEISER PIPE HANDLING APPARATUS Filed May 28., 1929 3 Sheets-Sheet 3 h m ante? E MIG-13w Attorney Patented June 17, 1930 UNITED STATES PIPE-HANDLING AIPARATUS Application filed May 28,

The present invention relates to an ap paratus in the form of an attachment for a conventional loader and caterpillar so that pipes may be handled in a reliable manner without the danger of injury in any rl nother very important object of the in vention resides in the provision of an apparatus of this nature which is comparati-vely simple in its construction, inexpensive to manufacture, strong and durable, convenient in its use, easy to engage and disengage in respect to the pipe and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view, as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of a conventional loader and caterpillar with my attaclnnent mounted thereon, Figure 2 is a top plan view thereof, Figure 3 is a front elevation of the apparatus, V

Figure 4 is a sectional view therethrough taken substantially on the line 4-4t of Figure 3, 1

Figure 5 is an enlarged detail elevation showing one end of the apparatus, and

Figure 6 is a sectional view therethrough. Referring to the drawing in detail it will be seen that the numeral 5 denotes generally a conventional loader and caterpillar which includes a pair of side swinging booms 6 having angular upwardly and forwardly inclined end portions 7 connected by a cross bar 8. I I

, Adjacent the extremities of these portions 7 I mount brackets 9 which hold in place 45 a transverse elongated pipe or bar 10 which extends well beyond the sides of the apparatus 5. Arms 11 project upwardly and incline rearwardly from the pipe or bar 10 one adjacent each portion 7. The caps 12 50 are threaded on the ends of the pipe 10 and 1929. Serial No.- 366,714

locked thereto by pins 14. These caps have laterally extending apertured ears 16 inclining upwardly and rearwardly and also horizontally outwardly disposed apertured cars 16.

A brace bar 17 extends through openings in the extremities of the arms 11 and through the gear 15 and nuts 18 are threadedly engaged on the extremities thereof so that the brace rod may be tightened. Wires 19 are engaged with the ears 16 and at'their ends have hooks 20.

Within the wires 19 adjacent theends are interposed binders or tighteners 21 to take up slack after the hooks have been engaged over the end edges of a pipe as is clearly illustrated in'Figure 5.

This attachment is mounted on the loader and caterpillar and is used for unloading pipe on a pipe line or may be used for loadin or unloading of any other material. With this attachment, the pipe can be picked up from trucks and placed at any position on the pipe line without damaging the pipe in anyway which often happens when pipe is dropped from the trucks.

With this attachment the pipe may be strung in any kind of rough country where it is impossible for trucks to go.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been disclosed in considerable detail merely for the'purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. 7

It will be apparent that the changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages. Having thus described my invention, what I claim as new is:

An attachment for a material handling apparatus embodying a boom having a pair of laterally spaced members, a horizontal bar extending across said base members and terminating substantial distances beyond the sides of the boom, the end portions of said bar being provided with caps having ears, a'truss vconnected to said ears andflexible elements connected to said caps and having pipe engaging devices and separate 7 tightening means to take up, the-slack in the flexible elements.
